Thanks for all your ideas and suggestions. I will think more about those, but for now I have reduced the timer to 5 hour and set minimum to 0.10 btc. As time goes on I will probably reduce the timer even further.

A: The person who last made a spend will instantly receive the entire jackpot. Then all spends will be cleared and the bubble game will start from scratch.

all spends meaning all un-popped bubbles? meaning you get nothing back if your bubble doesn't pop, before the timer runs out?

Yes You only receive profit if your bubble is bursted (or if you win jackpot). You are essentially buying advertising but with a chance of getting your advertising money returned (with profit) or actually winning a lot by being the last spender. It's named "bubble" since well.. all bubbles will eventually pop.

As you can see, all spends will currently be counted, so even if you use different receiving addresses it doesn't really decreases your chances... The way it's done now might be changed in the future though, I'm not sure if it will be good for the load when the bubble game grows big enough.

Once the lotto is won will the bubbles go in with the bursted bubbles or a separate category. I would prefer to see them in a separate category.

Once the bubble game is restarted all bubbles in that round will be removed from "bursted bubbles". It will start completely from scratch and last round will not be visible for users. I will add option to view last rounds jackpot and who won it, and maybe if there is enough demand I will also add the possibility to view bubbles (both bursted and non bursted).

Because its a lot of adding if its not on the first page, or a lot of subtracting from what is marked as needed to burst all bubbles on the last page.

So does the next round have to be set up manually or is it automated somehow?

Completely automated, but looks like you guys figured it out already seeing that the jackpot is already at 14 BTC

Jackpot is also supposed to be paid automatically, but it seems your jackpot money was NOT paid automatically (like it should), it tried to pay this address: "1Krbb2jqDDxvDHSFPPUBhM8S2Hz5M4PXe8"... is this correct?

Yes that's the correct address, and I was also wondering if that was supposed to be automated, because as you know, I haven't received it yet.
